In National Responsibility and Global Justice, David Miller defends the view that a member of a nation can be collectively responsible for an outcome despite the fact that: (i) she did not control it; (ii) she actively opposed those of her nation’s policies that produced the outcome; and (iii) actively opposing the relevant policy was costly for her. I argue that Miller’s arguments in favor of this strong externalist view about responsibility and control are insufficient. Specifically, I show that Miller’s two models of synchronic collective responsibility*the like-minded group model and the cooperative practice model*ground neither synchronic nor diachronic national responsibility, nor apply in the case of nations generally speaking.
